I also find that a bit confusing.
If you want to think about it in terms of quantum approach (i.e., individual
photons), the following points are worth keeping in mind:
(1) All of this is elastic scattering, falling within the first-order Born
approximation. What this means physically is a pho
Dear Mohamed
You can get the equivalent of frame.CBF by using the duals image viewer
with datablock or experiments.json and integrated.pickle. this will allow
you to step through the frames looking at the actual integration boxes.

The answer to your questions depends on the level of understanding of
quantum mechanics. I am sending info where to find the subject discussed
in more details.
Bernhard Rupp's book page 251 necessarily simplifies a rather complex
subject of the photon's interaction with multiple particles. Quantum
Excellent and interesting question—I’d love to hear an answer as well. Creatio
ex nihilo at the synchrotron?
I’d also love to hear what the evidence in the literature is for this, although
I suspect much of it would be hopelessly encoded in bristling equations.

Hello Everybody!
I was trying to make some sense from Bernhard Rupp's book page 251.
I will copy the relevant part...
When photons travel through a crystal, either of two things can happen: (i)
nothing, which happens over 99% of the time; (ii) the electric field vector
induces oscillations in al

Dear all
I can process my 3.8 A dataset in either P4 or P422 point groups. MR searches
and refinement in SG P41 and P41212 results in R/Rfree of around 30/35 % with 8

suggests 25 % twinning in the former (refinement

Perhaps one answer to the problem of using images might be to embed

Dear CCP4 Users
An update for the CCP4-6.5 series has just been released, consisting
of the following changes
* refmac5 (all platforms)
- various bug fixes and new program header2matr
* prosmart (all)
- fixed issue with degenerate PDB files
* pointless (all)
- 1.9.31, allow real-space rein
oh... I should have said that once saved, I can then insert the image where I
want in my doc(x).
